We are doing a
kit building project with the Orange County Amateur
Radio Club. We will be building the Small Wonder
Labs Retro-75 QRP AM Transceiver kit. I am an
instructor for this project, and built the kit to gain
an understanding of what is required. The Retro-75
is a cute little rig, puts out 2.5 Watts of carrier on
either 3880 or 3885, tunes the entire 75/80 Meter band,
and uses a varactor diode for tuning. It goes
together fairly easily, alignment is simple, and more
importantly, it works very well. And yes, you get
to wind the toroids yourself!
